Description:

Chromated copper arsenate (CCA) continues to be widely used as a wood preservative for industrial uses in the U.S. Disposal of treated wood is a potential long-term environmental liability. Current practices for disposing of decommissioned preservative-treated wood include landfilling and incineration, which are increasingly impractical due to environmental impacts. To date, however, research has not yielded commercially successful methods of recycling spent treated wood. Novel approaches are needed for the recycling of large quantities of decommissioned treated wood products. Engineering quality decommissioned preservative-treated wood for value-added, structural, industrial products will extend the service life of treated wood and would be a practical solution to the current disposal problems of treated wood. However, the bonding of decommissioned preservative-treated wood with synthetic resins for engineered products has not been investigated adequately. The objectives of this preliminary study were to (1) investigate CCA retention across and along decommissioned utility poles, (2) evaluate the effects of two surface preparation methods on improving bonding strength between treated wood, and (3) evaluate the effect of CCA retention on bonding strength of decommissioned treated wood. Results showed that CCA retention decreased from the outside to the inside and from the top to the bottom of the decommissioned poles of this study. CCA interfered with the bonding of treated wood after treatment with both priming and incising.
